Answer:
140 square inches
Step-by-step explanation:
An 8 inch by 6 inch rectangle would have a lateral area of 140 square inches.
7x - y= -5. Standard form is when it is written with x and y on the same side, but x is not negative or a fraction. To find the slope and y intercept, you must change the first two equations to slope intercept. You get y=7x-5 for the first one and y=11/3x+5 for the seccond equation. Take the 5 as your y intercept and the 7 as your slope and you get y=7x+5. Now you need to change it into standard form. When all is said and done, your final answer should be 7x - y = -5.

Answer:
Both equations equal 400.
(-50)(-8) = 400
50*8 = 400
Step-by-step explanation:
50*8 = 400 helps you find (-50)(-8) because (-a) = a. You simply must remove the parentheses. I hope this helps!
